The first awards for the IT-Harvest Cyber 150 went out last January. Let’s check in to see how they did. The purpose of pulling together this list was to demonstrate the value of a data-centric approach to studying the cyber security industry. We simply take a look at all the vendors in the size range of 50-500 people. Then we sort them by growth and take the top 150. If you were an investor or PE firm this would be a great place to start.
After a complete year:
These seven have graduated out of consideration for the 2026 award because they exceeded 500 people.
Cyera, the data security posture management (DSPM) leader grew 115% and just announced yet another round of $400 million, bringing their total investment to $1.7 billion. Calcalist reports they are valued at $9 billion.
With the Cyera investment the total received in 2025 for 39 of the Cyber 150 surpassed $4 billion. Over their collective lifetimes the Cyber 150 have taken in $11.5 billion in investments.
121 of these vendors continued to grow this past year. In 2024 they all grew over 24% but 29 of the 150 retrenched in 2025. Some are cause for concern and their investors should be calling for status updates. The biggest losers were actually all winners because the drop in headcount was the result of being acquired!
Check back in to see the 2026 Cyber 150 list shortly. Or, if you are a subscriber to the IT-Harvest Dashboard, you can set up a filter on companies between 50 and 500 employees and look at the top 150 fastest growing.
